The bottom surface of the projection unit 22 is attached to the housing 4 in contact with a mounting seat 34 provided on the bottom surface in the housing 4.

  Further, a detection unit 38 using a contact-type switch that detects that the projection unit 22 is mounted on the housing 4 is provided on the bottom surface in the housing 4. When this switch is on, it is detected that the projection unit 22 is mounted on the housing 4. On the other hand, when the switch is off, it is detected that the projection unit 22 has been removed from the housing 4.

  4 is a top sectional view showing the arrangement of units housed in the camera according to the embodiment, and FIG. 5 is a sectional view taken along line AA in FIG. As shown in FIG. 4, a main board 40 having a CPU 50 (see FIG. 6) is provided on the back side inside the housing 4. One end of the flat cable 44 is connected to the connector 42 provided on the main board 40, and the other end of the flat cable 44 is connected to the connector 46 provided on the projection unit 22. When the projection unit 22 is mounted on the housing 4, the flat cable 44 is folded and stored in a cable storage unit 23 (see FIG. 3) formed in a U-shaped space of the projection unit 22.

  FIG. 6 is a block diagram illustrating a system configuration of the camera according to the embodiment. The camera 2 includes a CPU 50. The CPU 50 includes an operation unit 52, a display control unit 54 that performs display control of the LCD display unit 24, a photographing lens (not shown), a photographing control unit 58 that controls driving of a shutter, and a subject. An image pickup unit 30 having the image pickup device, a buffer memory 60 for storing image data generated by A / D conversion of an image pickup signal output from the image pickup device in an A / D conversion unit (not shown), a picked-up image, and a projection image A memory card 62 for storing various data, a projection unit 22 for projecting images and various data stored in the buffer memory 60 and the memory card 62, and a detection unit 38 for detecting the attachment / detachment state of the housing 4 and the projection unit 22. Is connected.

  Here, the operation unit 52 includes a power switch 16, a release button 18, a PJ button 20, a multi selector 26, a volume control button 28, and the like, and the projection unit 22 is a power control unit that turns on and off the LED 64 that is a light source. 66. A projection control unit 70 that performs display control of the LCOS 68 that displays an image to be projected is provided.

  When projecting an image using the camera 2, the projection unit 22 is removed from the housing 4, and the projection unit 22 is installed at an optimal projection distance with respect to the projection plane. When the detection unit 38 detects that the projection unit 22 has been removed from the housing 4, the simultaneous mode in which the projection by the projection unit 22 and the imaging by the imaging unit 30 are performed simultaneously is set. Accordingly, the operator operates the multi-selector 26 on the back surface 8 of the housing 4 at a position away from the projection surface by an optimal distance, and displays the image on the LCD display unit 24 to determine the projection image while confirming the image. The projection unit 22 projects an image. In the case of an image in which sound is stored, the volume adjustment button 28 is operated to adjust the volume.

  According to the camera of this embodiment, the projection unit can be separated from the housing in a state where the projection unit and the control unit provided in the housing are connected by the flat cable. In this state, projection by the projection unit and imaging by the imaging unit can be performed simultaneously. Further, when the projection unit is mounted on the housing, it can be used as a normal digital camera. In addition, since the casing and the projection unit are connected with a flat cable, the projection unit can be prevented from being lost. Further, by removing the projection unit from the housing, it is set to a simultaneous mode in which projection and imaging are performed at the same time, so that favorable operability can be obtained.

  In the above-described embodiment, when the detection unit 38 detects that the projection unit 22 has been removed from the housing 4, the simultaneous mode in which imaging by the imaging unit 30 and projection by the projection unit 22 are performed simultaneously is set. However, when the projection unit 22 is removed from the casing 4, the simultaneous mode is set, or the projection mode in which only projection by the projection unit 22 is performed is set, or the multi selector 26 on the rear surface 8 of the casing 4 is set. Selection may be made by operating.

  Further, in the above-described embodiment, when the projection unit 22 is removed from the casing 4 and the projection by the projection unit 22 and the imaging by the imaging unit 30 are performed simultaneously, as shown in FIG. The projected image may be displayed on the first display unit 72 of the display unit, and the captured image may be displayed on the second display unit 74 at the same time. That is, the display control unit 54 displays the image projected by the projection unit 22 on the first display unit 72, and displays the image captured by the imaging unit 30 on the second display unit 74. Further, by operating the multi-selector 26 on the back surface 8 of the housing 4, either a projected image or a captured image may be selected, and the selected one may be displayed on the LCD display unit 24.

  In the above-described embodiment, when the projection unit 22 is removed from the housing 4 and the projection by the projection unit 22 and the imaging by the imaging unit 30 are performed simultaneously, the image is captured by the imaging unit 30 as shown in FIG. The projected image may be displayed on the LCD display unit 24 and the image may be projected by the projection unit 22 immediately.

  Further, in the above-described embodiment, when the projection unit 22 is removed from the housing 4 and the projection by the projection unit 22 and the imaging by the imaging unit 30 are performed simultaneously, as shown in FIG. May be provided with a first LCD display section 76 and a second LCD display section 78 on the upper surface, a captured image may be displayed on the first LCD display section 76, and a projected image may be displayed on the second LCD display section 78.

  In the above-described embodiment, when the projection unit 22 is removed from the housing 4 and projection by the projection unit 22 and imaging by the imaging unit 30 are performed simultaneously, when the imaging unit 30 performs imaging, the projection is performed. Instead of the image projected by the unit 22, an image captured by the imaging unit 30 may be projected by the projection unit 22.
